Ok i just started my motor up to get it ready for the season. It is a 40 hp evinrude. It was oil injected but that has since been bypassed so it runs off mixed.
The motor starts and runs good, but when I give it a decent amount of throttle, the motor takes off reving up, going Wide open throttle. And even if I pull the throttle back to neutral, it still goes full throttle. The key wont even shut off the motor when it does this. The only way to shut it off is to pull off the gas line.
I can start the motor again and it runs fine at less than half throttle. And, I can use the key to shut it off too. But as soon as I go past half throttle, the motor "takes off" and can not be controlled or shut off anymore.
The cables move freely, the throttle plates open and spring close smoothly, I sprayed carb cleaner to loosen any gunk, but it wasnt really dirty.
The only thing that i can think of it the gas. It is gas from last year. I dont know if that could make it do that or not. I still wouldnt undertand why i cant shut off the motor with the key.
If anyone has any ideas or can help in any way I would be greatly appreciative. I'm dying to get out on the water
Thanks, Tim
